Sign WallpaperThere's not a lot to explain about this. It's a wallpaper showcasing the recurrent sign motif of this site.
The sign motif is something I've got mixed feelings about. It seems to imply that I know the directions to somewhere or something... and I really don't. Anyone who browses this website long enough knows I'm pretty meandering, so maybe the sign motif is a reminder to myself to stay on the path.
